| 摘 要： | 为研究冰川消融期积累区的能量平衡,利用2006年6月21日-7月31日祁连山老虎沟12号冰川海拔5040 m气象观测资料,分析了冰川的能量平衡各分量变化特征,估算了冰川表面的能量平衡组成.结果表明:冰川消融期,净辐射是冰川的主要热量来源(占82.1%),其次是感热通量(占17.9%);冰川消融耗热是主要的能量支出项(占...

| Abstract: | Little is known about the surface energy balance in the accumulation zone of glaciers during the ablation period.In this paper,the characteristics of the components of the surface energy balance are analyzed,and the compositions of energy balance are estimated based on observed meteorological data from June 21 to July 31,2006,at an elevation of 5 040 meters of the Laohugou Glacier No.12 in the Qilian Mountains.It is found that during the ablation period,the net radiation is the principal energy source(82.1%... |
